➔ Check the USB Quick charging specifications.

In case of USB Quick charging, the quick charging mode varies by smartphone and PAD manufacturer.
In the case of the 34UC79G model, only products that meet the BC1.2 standards enable quick charging.

- Apple : Divider Mode
- Old and low-price models: Short Mode
- SS Galaxy Tab Model: 1.2V Mode
- Android and most models: BC (battery) 1.2

If the smartphone cannot be charged through the USB-C port of the monitor, reassemble or replace the C-C type monitor cable and check again.

Note
  • USB PD (Power Delivery) is a power delivery specification that supplies power to the USB-C port.
  • In the case of earlier USBs, only power supply up to 15W was possible, but cables supporting USB PD 4.0 can supply power up to 100W.
  • For monitors with USB PD specifications, the USB-C port can be used for charging and monitor output at the same time.
  • The amount of power supported may vary by monitor.
  • Since not all USB-C shaped adapters support USB PD, you can check whether or not USB-PD is supported in the product manual.
